How would one download a video with ScrapySharp?

Hi!
I have a very specific case, where I want to download a video from streamtape

• on this page there is a download button "downloadvideo" that if you click - it does a counter for a few seconds then it changes it href to the real download link

        var browser = new ScrapingBrowser();
        WebPage homePage = browser.NavigateToPage(new Uri("https://streamtape.com/v/9jzWrAdrJotDMD"));
        var firstDownloadButton = homePage.FindLinks(By.Id("downloadvideo"))
            .Single().Click();
  

? Don't know what to do next
